Traditional Method for Preparing Ro Spare Parts

Currently, more than 300 million people around the world rely on desalinated water to meet some or all of their daily needs. This demand will only grow as the population increases and living standards around the world increase.

However, access to the ocean for drinking water requires complex and expensive desalination techniques. The most common technique for desalination is reverse osmosis (RO), a process that forces seawater through a membrane that removes salts and other small molecular contaminants. Although the use of Ro Spare Parts(KOKOELECTRIC) continues to grow worldwide, many of its shortcomings, including high energy consumption and membrane fouling, continue to plague the industry.

In the latest issue of Science, researchers at the University of Connecticut offer a new membrane production method that allows us to rethink how to design and use desmotrope fittings for desalination.

Using additive manufacturing methods using electrospray, scientists at the University of Connecticut are able to create ultra-thin, ultra-smooth polyamide membranes that are less prone to fouling and may require less energy to allow water to flow through them.

The conventional method of making RO membranes has not changed in the past 40 years. The traditional method of making these films is called interfacial polymerization. This method relies on a self-terminating reaction between the aqueous phase amine and the organic phase acid chloride monomer. The resulting polyamide film is extremely thin, highly selective and water permeable, and becomes the gold standard film for RO. However, as the field develops, it is becoming more urgent to better control the reaction to allow membranes having different thicknesses and roughnesses to optimize water flow and reduce fouling.
